MegaETH contributed the following description of MegaETH Predeposit:

Protocol MegaUSDCDepositVault is a secure pre-deposit vault for USDC on Ethereum mainnet as part of the MegaETH onboarding. It verifies eligibility via off-chain--issued purchase permits, enforces time-windowed deposits and a global cap, binds each KYC'ed entityID to a single wallet, and lets the owner manage pause/cap/timing and withdraw funds to treasury for future bridging and USDm distribution.

Zellic conducted a security assessment for MegaETH from November 14th to November 17th, 2025. During this engagement, Zellic reviewed MegaETH Predeposit's code for security vulnerabilities, design issues, and general weaknesses in security posture.
